Product Details

The DiabloSport Modified PCM unlocks your vehicle's full performance potential by allowing you to load custom tune files. Factory PCMs are locked by the manufacturer to prevent alteration of stock calibrations, but this modified powertrain control module removes those limitations for 2015 and newer Chrysler, Dodge, Jeep, and Ram vehicles.

Key Features:

  • OEM-quality replacement PCM preprogrammed for your specific vehicle
  • Unlocked for use with DiabloSport tuning devices (inTune i3 or Trinity 2)
  • No core exchange required—keep your stock PCM as a backup
  • Enables custom tuning to optimize performance for aftermarket modifications
  • Compatible exclusively with DiabloSport tuning platforms

Important Installation Notes:

  • Requires a DiabloSport tuning device (sold separately) to install performance tunes
  • On 2019+ model year vehicles, you must save your stock calibration with a tuning device before removing the stock PCM
  • Vehicle VIN and 11-digit Calibration ID required for proper programming
  • Not compatible with other tuning brands

This modified PCM is specifically designed for 2021 Jeep Gladiator JT models equipped with the 3.6L V6 engine. It provides the foundation for unlocking additional horsepower and torque when paired with DiabloSport tuning software and performance modifications.
